Most of the online tutorials are written to close the interface directly, I figured out a way: binding two events at the same time
Example:
# Own method (self.register_re) # Close the interface ()
The code order represents the order of proceeding; the above example runs its own function first and then closes the current window.
Above this Pyqt5 to realize the jump interface and close the current interface is all that I have shared with you, I hope to be able to give you a reference, and I hope that you will support me more.
